Probing the Anomalous FCNC tqγ Couplings at Large Hadron Electron Collider

Advances in High Energy Physics, Volume 2017, Issue 1, 2017., 2017
We investigate the anomalous flavour changing neutral current (FCNC) interactions of top quark through the process e−p → e−W±q + X. We calculate the signal and background cross sections in electron‐proton collisions at Large Hadron electron Collider (LHeC) with a 7 TeV proton beam from the LHC and a new 60 GeV electron beam from energy recovery linac ...

KrkNLO Parton Shower Matching

Acta Physica Polonica B Proceedings Supplement
The consistent combination of Next-to-Leading-Order (NLO) perturbative QCD with the logarithmic resummation of parton shower algorithms (‘NLO matching’) is a workhorse of precision QCD in the LHC era. Two methods for achieving this have been widely adopted: Mc@Nlo and Powheg. The differences between them are formally Next-to-Next-to-Leading-Order (NNLO)

Parton showers and matching uncertainties in top quark pair production with Herwig 7

European Physical Journal C: Particles and Fields, 2019
We evaluate the theoretical uncertainties in next-to-leading order plus parton shower predictions for top quark pair production and decay in hadronic collisions.

Resampling algorithms for high energy physics simulations

European Physical Journal C: Particles and Fields, 2020
We demonstrate that the method of interleaved resampling in the context of parton showers can tremendously improve the statistical convergence of weighted parton shower evolution algorithms.

Summing threshold logs in a parton shower [PDF]

, 2016
When parton distributions are falling steeply as the momentum fractions of the partons increases, there are effects that occur at each order in $\alpha_s$ that combine to affect hard scattering cross sections and need to be summed.

Double Higgs production at NNLO interfaced to parton showers in GENEVA

Journal of High Energy Physics, 2023
In this work, we study the production of Higgs boson pairs at next-to-next-to-leading order in QCD matched to parton showers, using the Geneva framework and working in the heavy-top-limit approximation.
